Features

  • Unlike interference filters, which transmit only specific wavelengths, notch filters are filters that cut only specific wavelengths.
  • The *** of dielectric multilayer coatings provides extremely high environmental resistance and stability.
  • Available in 4 types for 355 nm, 532 nm, 633 nm and 1064 nm.
  • Beca*** of the dielectric multilayer coating, the film absorbs very little light.
  • It can also be ***d as a filter set for bioimaging by combining it with other filters.
  • * Transmittance wavelength characteristics may change when ***d at angles other than 0°. (In general, the larger the incident angle, the more the wavelength characteristic shifts toward the shorter wavelength.)
  • * The notch filter is designed to withstand high temperatures. However, safety and filter performance cannot be guaranteed if the notch filter is placed near a lamp (mercury lamp) that emits strong heat rays.
